The 2016 Optima Hybrid is a carryover model that's essentially unchanged from the 2015 version, even as non-hybrid 2016 Optimas launch with an entirely new architecture underneath--though you have to look extremely closely to tell.

This year's Optima Hybrid began shipping last November, but there are apparently still quite a few of the 2015 models left on dealer lots.

A redesigned 2017 Optima Hybrid is built on the new version--along with a first-ever plug-in hybrid model--was unveiled this week at the 2016 Chicago Auto Show, but it won't be available until later this year.

Buyers willing to settle for an outgoing design might also want to consider a leftover 2015 Toyota Prius instead of the new fourth-generation 2016 model.
